Hi Terri,
That looks like a really nice kit, by the way. I bet you could even find laser cut parts for it for things like formers and ribs. It does make things particularly exact, precise and takes a lot of the guess work out.
By the way...I think I use 160gm/cm2 paper. I got mine in A4 size from a now defunct stationary place on line. A4 is nice as that's sort of the standard for these models as most are from Poland, Russian, Bulgaria, the Czech Republic etc. The paper is thicker and tougher than typing paper but it is easy to form. I do some sanding of pieces to thin them for especially tight curves or to help hide seams.
Here is the latest. I got all my thicker parts on to 1/32nd balsa and have started the rear fuselage. Looking good so far!
Cheers,
Dan
